Detailed Description

Users of wide interest from various locations may capture digital images of various objects and make the captured images available to others via a network (e.g., the internet). To enhance a user's experience with digital images and provide various features, thereby enabling computing devices to perform image processing operations on various objects and/or features captured under various changing conditions (e.g., changes in image scale, noise, illumination, motion, or geometric distortion) can be challenging and computationally intensive.

As referred to herein, the phrases "augmented reality experience," "augmented reality content item," "augmented reality content generator," include or refer to various image processing operations corresponding to image modification, filtering, lens, media overlay, transformation, etc., as further described herein.

Fig. 1 is a block diagram illustrating an example messaging system 100 for exchanging data (e.g., messages and associated content) over a network. The messaging system 100 includes multiple instances of the client device 102, each instance hosting multiple applications including the messaging client application 104. Each messaging client application 104 is communicatively coupled to other instances of the messaging client application 104 and to a messaging server system 108 via a network 106 (e.g., the internet).

The messaging client application 104 is capable of communicating and exchanging data with another messaging client application 104 and a messaging server system 108 via a network 106. The data exchanged between the messaging client applications 104 and the messaging server system 108 includes functions (e.g., commands to invoke functions) and payload data (e.g., text, audio, video, or other multimedia data).

The messaging server system 108 provides server-side functionality to particular messaging client applications 104 via the network 106. Although certain functions of the messaging system 100 are described herein as being performed by the messaging client application 104 or by the messaging server system 108, the location of certain functions within the messaging client application 104 or the messaging server system 108 is a design choice. For example, it may be technically preferable to initially deploy certain techniques and functions within the messaging server system 108, but later migrate the techniques and functions to the messaging client application 104 where the client device 102 has sufficient processing power.

The messaging server system 108 supports various services and operations provided to the messaging client application 104. Such operations include sending data to the messaging client application 104, receiving data from the messaging client application 104, and processing data generated by the messaging client application 104. As examples, the data may include message content, client device information, geographic location information, media annotations and overlays, message content persistence conditions, social network information, and live event information. The exchange of data within the messaging system 100 is invoked and controlled by functions available via a User Interface (UI) of the messaging client application 104.

Turning now specifically to messaging server system 108, application Program Interface (API) server 110 is coupled to application server 112 and provides a programming interface to application server 112. The application server 112 is communicatively coupled to a database server 118 that facilitates access to a database 120 having stored therein data associated with messages processed by the application server 112.

An Application Program Interface (API) server 110 receives and transmits message data (e.g., command and message payloads) between the client device 102 and an application server 112. In particular, an Application Program Interface (API) server 110 provides a set of interfaces (e.g., routines and protocols) that may be invoked or queried by the messaging client application 104 to invoke the functionality of the application server 112. The Application Program Interface (API) server 110 exposes various functions supported by the application server 112, including account registration, login functions, sending messages from a particular messaging client application 104 to another messaging client application 104 via the application server 112, sending media files (e.g., images or videos) from the messaging client application 104 to the messaging server application 114 and possible access for the other messaging client application 104, setting of a set of media data (e.g., stories), retrieval of a buddy list of the user of the client device 102, retrieval of such a set, retrieval of messages and content, adding and deleting buddies to and from a social graph, location of buddies within a social graph, and opening application events (e.g., involving the messaging client application 104).

The application server 112 hosts a plurality of applications and subsystems, including a messaging server application 114, an image processing system 116, and a social networking system 122. The messaging server application 114 implements a number of message processing techniques and functions, particularly those related to the aggregation and other processing of content (e.g., text and multimedia content) included in messages received from multiple instances of the messaging client application 104. As will be described in further detail, text and media content from multiple sources may be aggregated into a collection of content (e.g., referred to as a story or library). The messaging server application 114 then makes these collections available to the messaging client application 104. Such processing may also be performed by the messaging server application 114 on the server side, taking into account the hardware requirements of other processors and memory intensive processing of the data.

The application server 112 also includes an image processing system 116, the image processing system 116 being dedicated to performing various image processing operations, typically with respect to images or videos received within the payload of a message at the messaging server application 114.

The social networking system 122 supports various social networking functionality services and makes these functions and services available to the messaging server application 114. To this end, social networking system 122 maintains and accesses an entity graph 304 (shown in FIG. 3) within database 120. Examples of functions and services supported by the social networking system 122 include identifying other users of the messaging system 100 with whom a particular user has a relationship or is "focused" by the particular user, and also identifying interests of the particular user, as well as other entities.

The application server 112 is communicatively coupled to a database server 118 that facilitates access to a database 120, with data associated with messages processed by the messaging server application 114 stored in the database 120.

Fig. 2 is a block diagram illustrating additional details regarding messaging system 100 according to an example embodiment. In particular, messaging system 100 is shown to include messaging client application 104 and application server 112, which in turn contain a plurality of subsystems, namely ephemeral timer system 202, collection management system 204, and annotation system 206.

The ephemeral timer system 202 is responsible for implementing temporary access to content allowed by the messaging client application 104 and the messaging server application 114. To this end, the ephemeral timer system 202 incorporates a plurality of timers that selectively display messages and associated content and enable access to the messages and associated content via the messaging client application 104 based on a duration and display parameters associated with the message or collection of messages (e.g., story). Additional details regarding the operation of the transient timer system 202 are provided below.

The collection management system 204 is responsible for managing collections of media (e.g., collections of text, image video, and audio data). In some examples, a collection of content (e.g., messages including images, video, text, and audio) may be organized into an "event gallery" or "event story. Such a collection may be made available for a specified period of time, such as the duration of an event to which the content relates. For example, content related to a concert may be made available as a "story" for the duration of the concert. The collection management system 204 may also be responsible for publishing icons that provide notifications to the user interface of the messaging client application 104 that a particular collection exists.

In addition, the collection management system 204 also includes a curation interface 208, the curation interface 208 enabling the collection manager to manage and curate a particular collection of content. For example, the curation interface 208 enables an event organizer to curate a collection of content related to a particular event (e.g., delete inappropriate content or redundant messages). In addition, the collection management system 204 employs machine vision (or image recognition techniques) and content rules to automatically curate the collection of content. In some implementations, compensation can be paid to the user to include the user-generated content into the collection. In such a case, curation interface 208 operates to automatically pay such users for use of their content.

The annotation system 206 provides various functions that enable a user to annotate or otherwise modify or edit media content associated with a message. For example, the annotation system 206 provides functionality related to generating and publishing media overlays for messages processed by the messaging system 100. The annotation system 206 is operable to supply media overlays or supplements (e.g., image filtering) to the messaging client application 104 based on the geographic location of the client device 102. In another example, the annotation system 206 is operable to provision the messaging client application 104 with a media overlay based on other information (e.g., social network information of a user of the client device 102). The media overlay may include audio and visual content and visual effects. Examples of audio and visual content include pictures, text, logos, animations and sound effects. Examples of visual effects include color overlays. Audio and visual content or visual effects may be applied to media content items (e.g., photos) at the client device 102. For example, the media overlay may include text that may be overlaid on top of a photograph taken by the client device 102. In another example, the media overlay includes a location identification (e.g., a Venetian beach overlay), a name of a live event, or a merchant name (e.g., a beach cafe) overlay. In another example, annotation system 206 uses the geographic location of client device 102 to identify a media overlay that includes a merchant name at the geographic location of client device 102. The media overlay may include other indicia associated with the merchant. The media overlay may be stored in database 120 and accessed through database server 118.

In one example implementation, the annotation system 206 provides a user-based distribution platform that enables a user to select a geographic location on a map and upload content associated with the selected geographic location. The user may also specify the environment in which the particular media overlay should be provided to other users. The annotation system 206 generates a media overlay that includes the uploaded content and associates the uploaded content with the selected geographic location.

In another example embodiment, the annotation system 206 provides a merchant-based posting platform that enables merchants to select particular media overlays associated with geographic locations through a bidding process. For example, the annotation system 206 associates the media overlay of the highest bidding merchant with the corresponding geographic location within a predefined amount of time.

Fig. 3 is a schematic diagram illustrating a data structure 300 that may be stored in the database 120 of the messaging server system 108, according to some example embodiments. Although the contents of database 120 are shown as including multiple tables, it should be understood that the data may be stored in other types of data structures (e.g., as an object-oriented database).

Database 120 includes message data stored within message table 314. Entity table 302 stores entity data, including entity map 304. The entities maintaining records within the entity table 302 may include individuals, corporate entities, organizations, objects, places, events, and the like. Regardless of the type, any entity that stores data with respect to the messaging server system 108 may be an identified entity. Each entity is provided with a unique identifier and an entity type identifier (not shown).

Entity map 304 also stores information about relationships and associations between entities. By way of example only, such relationships may be social relationships, professional relationships (e.g., work at a common company or organization) based on interest or activity.

Database 120 also stores annotation data in annotation table 312 in the example form of filters. Filters storing data within annotation table 312 are associated with and applied to video (data stored in video table 310) and/or images (data stored in image table 308). In one example, the filter is an overlay that is displayed as an overlay over the image or video during presentation to the receiving user. The filters may be of various types, including user-selected filters from a library of filters that are presented to the sending user by the messaging client application 104 when the sending user is composing a message. Other types of filters include geo-location filters (also referred to as geo-filters) that may be presented to a sending user based on geographic location. For example, based on geographic location information determined by a GPS unit of the client device 102, the messaging client application 104 may present a neighborhood-specific or location-specific geographic location filter within the user interface. Another type of filter is a data filter that may be selectively presented to the sending user by the messaging client application 104 based on other inputs or information collected by the client device 102 during the message creation process. Examples of data filters include a current temperature at a particular location, a current speed at which a sending user travels, a battery life of the client device 102, or a current time.

Other annotation data that may be stored within the image table 308 is an augmented reality content generator (e.g., corresponding to an application lens, an augmented reality experience, or an augmented reality content item). The augmented reality content generator may be real-time special effects and sounds that may be added to an image or video.

As described above, augmented reality content generator, augmented reality content item, overlay, image transformation, AR image, and similar terms refer to modifications that may be made to a video or image. This includes real-time modification, which modifies an image as it is captured using a device sensor, and then displays the image with the modification on a screen of the device. This also includes modifications to the stored content, such as video clips in a library that may be modified. For example, in a device accessing multiple augmented reality content generators, a user may use a single video clip with multiple augmented reality content generators to see how different augmented reality content generators will modify the stored clips. For example, by selecting different augmented reality content generators for content, multiple augmented reality content generators applying different pseudo-random motion models may be applied to the same content. Similarly, real-time video capture may be used with the illustrated modifications to show how the video image currently captured by the device's sensor will modify the captured data. Such data may simply be displayed on the screen without being stored in memory, or content captured by the device sensor may be recorded and stored in memory with or without modification (or both). In some systems, the preview feature may show how different augmented reality content generators look within different windows in the display at the same time. For example, this may enable multiple windows with different pseudo-random animations to be viewed simultaneously on a display.

Thus, the data and various systems that use the augmented reality content generator or other such transformation system to modify the content using the data may involve: detection of a subject (e.g., face, hand, body, cat, dog, surface, subject, etc.); tracking such objects as they leave, enter, and move around the field of view in the video frame; and modifying or transforming such objects as they are tracked. In various embodiments, different methods for implementing such transformations may be used. For example, some embodiments may involve generating a three-dimensional mesh model of one or more objects and implementing the transformation using a transformation of the model in the video and an animated texture. In other embodiments, tracking of points on an object may be used to place an image or texture (which may be two-dimensional or three-dimensional) at the tracked location. In yet another embodiment, neural network analysis of video frames may be used to place images, models, or textures in content (e.g., images or frames of video). Thus, the augmented reality content generator involves both images, models, and textures for creating transformations in the content, and additional modeling and analysis information required to implement such transformations with object detection, tracking, and placement.

Real-time video processing may be performed using any kind of video data (e.g., video streams, video files, etc.) stored in the memory of any kind of computerized system. For example, a user may load a video file and save it in the memory of the device, or may generate a video stream using a sensor of the device. In addition, computer animation models may be used to process any object, such as a human face and parts of a human body, animals, or inanimate objects (e.g., chairs, automobiles, or other objects).

In some implementations, when a particular modification is selected along with the content to be transformed, the element to be transformed is identified by the computing device and then detected and tracked if the element to be transformed is present in a frame of the video. The elements of the object are modified according to the modification request, thus transforming the frames of the video stream. The transformation of frames of the video stream may be performed by different methods for different kinds of transformations. For example, for transformations of frames that primarily involve changing the form of an object element, feature points for each element of the object are computed (e.g., using an Active Shape Model (ASM) or other known methods). Then, a feature point-based mesh is generated for each of the at least one element of the object. The grid is used to track subsequent stages of object elements in the video stream. During the tracking process, the grid of each element is referred to as being aligned with the location of each element. Additional points are then generated on the grid. A first set of first points is generated for each element based on the modification request and a set of second points is generated for each element based on the set of first points and the request for modification. The frames of the video stream may then be transformed by modifying the elements of the object based on the set of first points and the set of second points and the grid. In such methods, the background of the modified object may also be changed or deformed by tracking and modifying the background.

In one or more embodiments, transformation of some regions of the changed object using elements of the object may be performed by calculating feature points of each element of the object and generating a mesh based on the calculated feature points. Points are generated on the grid, and then various areas based on the points are generated. The elements of the object are then tracked by aligning the region of each element with the location of each of the at least one element, and the attributes of the region may be modified based on the request for modification, thereby transforming the frames of the video stream. The properties of the mentioned areas may be transformed in different ways depending on the specific modification request. Such modification may involve changing the color of the region; removing at least some portions of the region from frames of the video stream; including one or more new objects into the region based on the request for modification; and modifying or deforming the elements of the region or object. In various embodiments, any combination of such modifications or other similar modifications may be used. For some models to be animated, some feature points may be selected as control points for determining the entire state space for the options for model animation.

In some embodiments of computer-animated models that use face detection to transform image data, a particular face detection algorithm (e.g., viola-Jones) is used to detect faces on the image. An Active Shape Model (ASM) algorithm is then applied to the facial regions of the image to detect facial feature reference points.

In other embodiments, other methods and algorithms suitable for face detection may be used. For example, in some embodiments, landmarks are used to locate features, which represent distinguishable points present in most of the images considered. For example, for facial landmarks, the localization of the left eye pupil may be used. In the case where the initial landmarks are not identifiable (e.g., if a person has eye shields), secondary landmarks may be used. Such a landmark identification procedure may be used for any such object. In some embodiments, the collection of landmarks forms a shape. The coordinates of points in the shape may be used to represent the shape as a vector. One shape is aligned with another shape using a similarity transformation (allowing translation, scaling, and rotation) that minimizes the average euclidean distance between shape points. The average shape is the average of the aligned training shapes.

In some implementations, searching for landmarks from the average shape aligned with the position and size of the face determined by the global face detector begins. Then, such search repeats the steps of: the tentative shape is suggested by adjusting the positioning of the shape points by template matching of the image texture around each point, and then conforming the tentative shape to the global shape model until convergence occurs. In some systems, single template matching is unreliable and the shape model concentrates the results of the weak template matcher together, forming a stronger overall classifier. The entire search is repeated at each level of the image pyramid from coarse resolution to fine resolution.

Embodiments of the transformation system may capture images or video streams on a client device (e.g., client device 102) and perform complex image manipulation locally on the client device 102 while maintaining an appropriate user experience, computation time, and power consumption. Complex image manipulation may include size and shape changes, mood transfers (e.g., changing a face from frowning to smiling), state transfers (e.g., aging a subject, reducing apparent age, changing gender), style transfers, graphic element applications, and any other suitable image or video manipulation implemented by a convolutional neural network that has been configured to be efficiently performed on the client device 102.

In some example implementations, a computer animation model for transforming image data may be used by a system in which a user may capture an image or video stream (e.g., a self-shot) of the user using a client device 102 having a neural network that operates as part of a messaging client application 104 operating on the client device 102. A transformation system operating within messaging client application 104 determines the presence of faces within an image or video stream and provides a modification icon associated with a computer animation model to transform image data, or the computer animation model may exist in association with an interface described herein. The modification icon includes a change that may be the basis for modifying a user's face in an image or video stream as part of a modification operation. Once the modification icon is selected, the transformation system initiates a process for converting the image of the user to reflect the selected modification icon (e.g., to generate a smiley face for the user). In some implementations, once an image or video stream is captured and a specified modification is selected, the modified image or video stream can be presented in a graphical user interface displayed on the mobile client device. The transformation system may implement a complex convolutional neural network on a portion of the image or video stream to generate and apply the selected modifications. That is, once the modification icon is selected, the user may capture an image or video stream and be presented with the results of the modification in real-time or near real-time. Further, the modification may be persistent while the video stream is captured and the selected modification icon remains open. A neural network of machine teachings may be used to implement such modifications.

In some implementations, presenting a modified graphical user interface performed by the transformation system can provide additional interaction options for the user. Such options may be based on the interface used to initiate content capture and selection of a particular computer animation model (e.g., initiated from a content creator user interface). In various embodiments, the modification may persist after the initial selection of the modification icon. The user may turn the modification on or off by tapping or otherwise selecting the face modified by the transformation system and store it for later viewing or browsing to other areas of the imaging application. In the case of multiple faces modified by the transformation system, the user may globally turn the modification on or off by tapping or selecting a single face modified and displayed within the graphical user interface. In some implementations, individual faces among a set of multiple faces can be individually modified by tapping or selecting an individual face or a series of individual faces displayed within a graphical user interface, or such modification can be individually turned on.

In some example implementations, a graphics processing pipeline architecture is provided that enables different augmented reality experiences (e.g., AR content generators) to be applied in corresponding different layers. Such a graphics processing pipeline provides an extensible rendering engine for providing multiple augmented reality experiences included in a composite media (e.g., image or video) for presentation by a messaging client application 104 (or messaging system 100).

As mentioned above, video table 310 stores video data, which in one embodiment is associated with messages whose records are maintained in message table 314. Similarly, the image table 308 stores image data associated with messages about which the message data is stored in the entity table 302. The entity table 302 may associate various annotations from the annotation table 312 with various images and videos stored in the image table 308 and the video table 310.

Story table 306 stores data regarding a collection of messages and associated image, video, or audio data that is compiled into a collection (e.g., a story or library). Creation of a particular collection may be initiated by a particular user (e.g., each user whose record is maintained in the entity table 302). A user may create a "personal story" in the form of a collection of content that has been created and transmitted/broadcast by the user. To this end, the user interface of the messaging client application 104 may include an icon that a user can select to enable the sending user to add particular content to his or her personal story.

The collection may also constitute a "live story" which is a collection of content from multiple users that is created manually, automatically, or using a combination of manual and automatic techniques. For example, a "live story" may constitute a curated stream of user-submitted content from different locations and events. Users whose client devices have location services enabled and are at co-located events at a particular time may be presented with options to contribute content to a particular live story, for example, via a user interface of messaging client application 104. The live story may be identified to the user by the messaging client application 104 based on the user's location. The end result is a "live story" told from a community perspective.

Another type of collection of content is referred to as a "location story" that enables users whose client devices 102 are located within a particular geographic location (e.g., at a university or college campus) to contribute to the particular collection. In some implementations, the contribution to the location story may require a second degree of authentication to verify that the end user belongs to a particular organization or other entity (e.g., is a student in a university campus).

Fig. 4 is a schematic diagram illustrating the structure of a message 400, the message 400 generated by a messaging client application 104 for transmission to another messaging client application 104 or messaging server application 114, in accordance with some embodiments. The contents of a particular message 400 are used to populate a message table 314 stored in the database 120, which is accessible by the messaging server application 114. Similarly, the content of message 400 is stored in memory as "in-transit" or "in-flight" data for client device 102 or application server 112. Message 400 is shown to include the following components:

message identifier 402: a unique identifier that identifies the message 400.

Message text payload 404: text to be generated by a user via a user interface of the client device 102 and included in the message 400.

Message image payload 406: image data captured by the camera component of the client device 102 or retrieved from the memory component of the client device 102 and included in the message 400.

Message video payload 408: video data captured by the camera assembly component or retrieved from the memory component of the client device 102 and included in the message 400.

Message audio payload 410: audio data captured by the microphone or retrieved from a memory component of the client device 102 and included in the message 400.

Message annotation 412: annotation data (e.g., filters, stickers, or other enhancements) representing annotations to be applied to the message image payload 406, the message video payload 408, or the message audio payload 410 of the message 400.

Message duration parameter 414: parameter values indicating, in seconds, the content of the message (e.g., message image payload 406, message video payload 408, message audio payload 410) will be presented to the user via the messaging client application 104 or the amount of time that the user is made accessible.

Message geographic location parameter 416: geographic location data (e.g., latitude and longitude coordinates) associated with the content payload of the message. A plurality of message geographic location parameter values 416 may be included in the payload, each of which is associated with a content item included in the content (e.g., a particular image within the message image payload 406 or a particular video within the message video payload 408).

Message story identifier 418: an identifier value that identifies one or more collections of content (e.g., "stories") associated with a particular content item in the message image payload 406 of the message 400. For example, multiple images within the message image payload 406 may each be associated with multiple sets of content using an identifier value.

Message tag 420: each message 400 may be tagged with a plurality of tags, each tag of the plurality of tags indicating the subject matter of the content included in the message payload. For example, where a particular image included in the message image payload 406 depicts an animal (e.g., a lion), the tag value may be included within the message tag 420 indicating the relevant animal. The tag value may be generated manually based on user input or may be generated automatically using, for example, image recognition.

Message sender identifier 422: an identifier (e.g., a messaging system identifier, an email address, or a device identifier) indicating the user of the client device 102 on which the message 400 was generated and from which the message 400 was sent.

Message recipient identifier 424: an identifier (e.g., a messaging system identifier, an email address, or a device identifier) indicating the user of the client device 102 to which the message 400 is addressed

The contents (e.g., values) of the various components of message 400 may be pointers to locations in a table in which the content data values are stored. For example, the image value in the message image payload 406 may be a pointer to a location (or address) within the image table 308. Similarly, values within message video payload 408 may point to data stored within video table 310, values stored in message notes 412 may point to data stored in notes table 312, values stored in message story identifier 418 may point to data stored in story table 306, and values stored in message sender identifier 422 and message receiver identifier 424 may point to user records stored within entity table 302.

Fig. 5 is a schematic diagram illustrating an access restriction process 500 according to which access to content (e.g., a multimedia payload of ephemeral messages 502 and associated data) or a collection of content (e.g., ephemeral message groups 504) may be time-limited (e.g., ephemeral).

The ephemeral message 502 is shown as being associated with a message duration parameter 506, the value of the message duration parameter 506 determining the amount of time that the messaging client application 104 will display the ephemeral message 502 to the receiving user of the ephemeral message 502. In one embodiment, the receiving user may view the ephemeral message 502 for up to 10 seconds, depending on the amount of time the sending user has specified using the message duration parameter 506.

The message duration parameter 506 and the message recipient identifier 424 are shown as inputs to a message timer 512, which message timer 512 is responsible for determining the amount of time that the ephemeral message 502 is shown to a particular receiving user identified by the message recipient identifier 424. In particular, the transient message 502 is only shown to the relevant receiving user for a period of time determined by the value of the message duration parameter 506. The message timer 512 is shown to provide output to a more generalized ephemeral timer system 202, which ephemeral timer system 202 is responsible for overall timing of the display of content (e.g., ephemeral message 502) to a receiving user.

Ephemeral messages 502 are shown in fig. 5 as being included within an ephemeral message group 504 (e.g., collection of messages in a personal story or an event story). The ephemeral message group 504 has an associated group duration parameter 508, the value of the group duration parameter 508 determining the duration that the ephemeral message group 504 is presented and accessible by a user of the messaging system 100. For example, the group duration parameter 508 may be the duration of a concert, where the ephemeral message group 504 is a collection of content belonging to the concert. Alternatively, the user (owning user or curator user) may specify the value of the group duration parameter 508 when performing the setting and creation of the ephemeral message group 504.

In addition, each ephemeral message 502 within the ephemeral message group 504 has an associated group participation parameter 510, the value of the group participation parameter 510 determining the duration of time that the ephemeral message 502 is accessible within the context of the ephemeral message group 504. Thus, before the ephemeral message group 504 itself expires according to the group duration parameter 508, a particular ephemeral message group 504 may "expire" and become inaccessible in the context of the ephemeral message group 504. The group duration parameter 508, the group participation parameter 510, and the message recipient identifier 424 each provide input to the group timer 514, and the group timer 514 is operable to first determine whether a particular ephemeral message 502 of the ephemeral message group 504 is to be displayed to a particular receiving user, and if so, how long to display. Note that the ephemeral message group 504 also knows the identity of the particular receiving user as a result of the message recipient identifier 424.

Thus, the group timer 514 is operable to control the total lifetime of the associated ephemeral message group 504 and the individual ephemeral messages 502 included in the ephemeral message group 504. In one embodiment, each ephemeral message 502 within the ephemeral message group 504 remains viewable and accessible for a period of time specified by the group duration parameter 508. In another embodiment, within the context of the ephemeral message group 504, a certain ephemeral message 502 may expire based on the group participation parameter 510. Note that even within the context of the ephemeral message group 504, the message duration parameter 506 may still determine the duration of displaying the particular ephemeral message 502 to the receiving user. Thus, the message duration parameter 506 determines the duration of displaying a particular ephemeral message 502 to a receiving user, regardless of whether the receiving user views the ephemeral message 502 within or outside the context of the ephemeral message group 504.

The ephemeral timer system 202 may also be operable to remove a particular ephemeral message 502 from the ephemeral message group 504 based on determining that the associated group participation parameter 510 has been exceeded. For example, when the sending user has established a group participation parameter 510 of 24 hours from release, the ephemeral timer system 202 will remove the relevant ephemeral message 502 from the ephemeral message group 504 after the specified 24 hours. The ephemeral timer system 202 also operates to remove the ephemeral message group 504 when the group participation parameter 510 for each ephemeral message 502 within the ephemeral message group 504 has expired, or when the ephemeral message group 504 itself has expired according to the group duration parameter 508.

In some use cases, the creator of a particular ephemeral message group 504 may specify an deadline group duration parameter 508. In this case, the expiration of the group participation parameter 510 for the last remaining ephemeral message 502 within the ephemeral message group 504 will determine when the ephemeral message group 504 itself has expired. In this case, the new ephemeral message 502 with the new group participation parameter 510 added to the ephemeral message group 504 effectively extends the lifetime of the ephemeral message group 504 to be equal to the value of the group participation parameter 510.

In response to the ephemeral timer system 202 determining that the ephemeral message group 504 has expired (e.g., is no longer accessible), the ephemeral timer system 202 communicates with the messaging system 100 (and, in particular, the messaging client application 104, for example) such that a logo (e.g., icon) associated with the relevant ephemeral message group 504 is no longer displayed within the user interface of the messaging client application 104. Similarly, when the ephemeral timer system 202 determines that the message duration parameter 506 for a particular ephemeral message 502 has expired, the ephemeral timer system 202 causes the messaging client application 104 to no longer display a flag (e.g., an icon or text identification) associated with the ephemeral message 502.

As described above, media overlays such as lines, overlays, image transforms, AR images, and similar terms refer to modifications that may be made to a video or image. This includes real-time modification, which modifies an image as it is captured using a device sensor, and then displays the image with the modification on a screen of the device. This also includes modifications to stored content, such as video clips in a library, that may be modified. For example, in a device accessing multiple media overlays (e.g., LENSES), a user may use a single video clip with multiple LENSES to see how different LENSES will modify the stored clip. For example, by selecting different LENSES for the same content, multiple LENSES that apply different pseudorandom motion models may be applied to the same content. Similarly, real-time video capture may be used with the illustrated modifications to show how the video image currently captured by the device's sensor will modify the captured data. Such data may simply be displayed on the screen without being stored in memory, or content captured by the device sensor may be recorded and stored in memory with or without modification (or both). In some systems, the preview function may show how different LENSES look at different windows of the display at the same time. For example, this may enable multiple windows with different pseudo-random animations to be viewed simultaneously on a display.

The data and the various systems that use the LENSES or other such transformation system to modify the content using the data may thus involve: detection of a subject (e.g., face, hand, body, cat, dog, surface, subject, etc.); tracking such objects as they leave, enter, and move around the field of view in the video frame; and modifications or transformations to such objects as they are tracked. In various embodiments, different methods for implementing such transformations may be used. For example, some embodiments may involve generating a three-dimensional mesh model of one or more objects and implementing the transformation using a transformation of the model in the video and an animated texture. In other embodiments, tracking of points on an object may be used to place an image or texture (which may be two-dimensional or three-dimensional) at the tracked location. In still further embodiments, neural network analysis of video frames may be used to place images, models, or textures in content (e.g., images or video frames). Thus, shot (lens) data involves both images, models, and textures used to create content transformations, and additional modeling and analysis information required to implement such transformations through object detection, tracking, and placement.

Real-time video processing may be performed using any kind of video data (e.g., video streams, video files, etc.) stored in the memory of any kind of computerized system. For example, a user may load a video file and save it in the memory of the device, or may generate a video stream using a sensor of the device. In addition, computer animation models may be used to process any object, such as parts of a human face and body, animals, or inanimate objects, such as chairs, automobiles, or other objects.

In some implementations, when a particular modification is selected along with the content to be transformed, the element to be transformed is identified by the computing device and then detected and tracked if the element to be transformed is present in a frame of the video. The elements of the object are modified according to the modification request, thus transforming the frames of the video stream. The transformation of frames of the video stream may be performed by different methods for different kinds of transformations. For example, for frame transforms that primarily involve changing the form of an object element, feature points for each of the elements of the object are computed (e.g., using an Active Shape Model (ASM) or other known methods). Then, a feature point-based mesh is generated for each of the at least one element of the object. The grid is used to track subsequent stages of object elements in the video stream. During the tracking process, the grid of each element is referred to as being aligned with the location of each element. Additional points are then generated on the grid. A first set of first points is generated for each element based on the modification request and a set of second points is generated for each element based on the set of first points and the request for modification. The frames of the video stream may then be transformed by modifying the elements of the object based on the set of first points and the set of second points and the grid. In such methods, the background of the modified object may also be changed or deformed by tracking and modifying the background.

In one or more embodiments, transformation of some regions of the changed object using elements of the object may be performed by calculating feature points of each element of the object and generating a mesh based on the calculated feature points. Points are generated on the grid, and then various areas based on the points are generated. The elements of the object are then tracked by aligning the region of each element with the location of each of the at least one element, and the attributes of the region may be modified based on the request for modification, thereby transforming the frames of the video stream. The properties of the mentioned areas may be transformed in different ways depending on the specific modification request. Such modifications may involve: changing the color of the region; removing at least some portions of the region from frames of the video stream; including one or more new objects in the modification request-based region; and modifying or deforming an element of the region or object. In various embodiments, any combination of such modifications or other similar modifications may be used. For some models to be animated, some feature points may be selected as control points for determining the entire state space for the options for model animation.

In other embodiments, other methods and algorithms suitable for face detection may be used. For example, in some embodiments, landmarks are used to locate features, which represent distinguishable points present in most of the images considered. For example, for facial landmarks, the position of the left eye pupil may be used. In the case where the initial landmarks are not identifiable (e.g., if a person has eye masks), secondary landmarks may be used. Such a landmark identification procedure may be used for any such object. In some embodiments, the collection of landmarks forms a shape. The coordinates of points in the shape may be used to represent the shape as a vector. One shape is aligned with another shape using a similarity transformation (allowing translation, scaling, and rotation) that minimizes the average euclidean distance between shape points. The average shape is the average of the aligned training shapes.

Embodiments of the transformation system may capture an image or video stream on a client device and perform complex image manipulation locally on the client device, such as client device 102, while maintaining an appropriate user experience, computation time, and power consumption. Complex image manipulation may include size and shape changes, mood migration (e.g., changing a face from frowning to smiling), state migration (e.g., aging a subject, reducing apparent age, changing gender), style migration, graphic element application, and any other suitable image or video manipulation implemented by a convolutional neural network that has been configured to be efficiently performed on a client device.

In some implementations, presenting a modified graphical user interface performed by the transformation system can provide additional interaction options for the user. Such options may be based on the interface used to initiate content capture and selection of a particular computer animation model (e.g., initiation from a content creator user interface). In various embodiments, the modification may persist after the initial selection of the modification icon. The user may turn the modification on or off by tapping or otherwise selecting the face modified by the transformation system and store it for later viewing or browsing to other areas of the imaging application. In the case of multiple faces modified by the transformation system, the user may globally turn the modification on or off by tapping or selecting a single face modified and displayed within the graphical user interface. In some implementations, individual faces among a set of multiple faces can be individually modified by tapping or selecting an individual face or a series of individual faces displayed within a graphical user interface, or such modification can be individually turned on.

In some example implementations, a graphics processing pipeline architecture is provided that enables different media overlays to be applied in corresponding different layers. Such a graphics processing pipeline provides an extensible rendering engine for providing multiple augmented reality content generators included in a composite media (e.g., image or video) for presentation by a messaging client application 104 (or messaging system 100).

As discussed herein, the subject infrastructure supports creating and sharing interactive messages with interactive effects among the various components of the messaging system 100. In an example, to provide such an interactive effect, a given interactive message may include image data and 2D data or 3D data. The infrastructure as described herein enables other forms of 3D and interactive media (e.g., 2D media content) to be provided across the subject system, which allows such interactive media to be shared across the messaging system 100 and with photo and video messages. In example implementations described herein, a message may enter the system from a real-time camera or via a storage device (e.g., a message with 2D or 3D content or Augmented Reality (AR) effects (e.g., 3D effects or other interactive effects) is stored in a memory or database). In the example of an interactive message with 3D data, the subject system would support motion sensor input and manage the sending and storage of 3D data, as well as the loading of external effects and asset data.

As described above, the interactive message includes an image combining the 2D effect or the 3D effect and the depth data. In an example embodiment, the subject system is used to render messages to visualize the spatial details/geometry seen by the camera, in addition to conventional image textures. When a viewer interacts with the message by moving the client device, the motion triggers a corresponding change in the viewer's perspective of the rendered image and geometry.

In an embodiment, the subject system provides the following AR effects (which may include 3D effects using 3D data or interactive 2D effects not using 3D data): which works with other components of the system to provide 3D geometry, particles, shaders, and 2D assets that can occupy different 3D planes in the message. In an example, the AR effects described herein are rendered to a user in real-time.

As referred to herein, gyroscope-based interactions refer to the type of interaction in which rotation of a given client device is used as input to change aspects of an effect (e.g., rotating a phone along the x-axis in order to change the color of light in a scene).

As referred to herein, an augmented reality content generator refers to real-time special effects and/or sounds that can be added to a message, and modify images and/or 3D data with AR effects and/or other 3D content (e.g., 3D animated graphical elements), 3D objects (e.g., non-animations), etc.

The following discussion relates to example data stored in connection with such messages, according to some embodiments.

Fig. 6 is a schematic diagram illustrating the structure of a message annotation 412 as described above in fig. 4 that includes additional information corresponding to a given message, generated by the messaging client application 104, in accordance with some embodiments.

In an embodiment, the contents of a particular message 400 including additional data as shown in FIG. 6, as shown in FIG. 3, are used to populate a message table 314 for a given message stored within the database 120, which database 120 is then accessible by the messaging client application 104. As shown in fig. 6, the message annotation 412 includes the following components corresponding to various data:

augmented Reality (AR) content identifier 652: identifier of AR content generator used in message

Message identifier 654: identifier of message

Asset identifier 656: a collection of identifiers of assets in a message. For example, a corresponding asset identifier may be included for an asset determined by a particular AR content generator. In an embodiment, such assets are created by the AR content generator of the sender-side client device, uploaded to the messaging server application 114, and used on the receiver-side client device to recreate the message. Examples of typical assets include:

■ Original static RGB image captured by camera device

■ Post-processing image with AR content generator effect applied to original image

Augmented Reality (AR) content metadata 658: additional metadata associated with the AR content generator corresponding to AR identifier 652, such as:

Class of AR content generator: type or class corresponding to a particular AR content generator

O AR content generator carousel index

Transfer band group: the band set may be populated and used when the eligible post-capture AR content generator is inserted into the band interface. In an implementation, a new value "ar_default_group" (e.g., a DEFAULT GROUP assigned to a particular AR content generator) may be added to the active GROUP name list and other selected AR content generators may be included in the GROUP.

Captured metadata 660 corresponding to the additional metadata, for example:

image metadata of image pickup device

■ Internal data of image pickup device

Focal length

Principal point

■ Other camera information (e.g., camera positioning)

Sensor information

■ Gyroscopic sensor data

■ Positioning sensor data

■ Accelerometer sensor data

■ Other sensor data

■ Position sensor data

Fig. 7 is a block diagram 700 illustrating various modules of the annotation system 206 according to some example embodiments. The annotation system 206 is shown to include an image data receiving module 702, a sensor data receiving module 704, an image data processing module 706, an Augmented Reality (AR) effects module 708, a rendering module 710, and a sharing module 712. The various modules of annotation system 206 are configured to communicate with each other (e.g., via a bus, shared memory, or switch). Any one or more of these modules may be implemented using one or more computer processors 720 (e.g., by configuring such one or more computer processors to perform the functions described for the module), and thus may include one or more of the computer processors 720 (e.g., a collection of processors provided by client device 102).

Any one or more of the described modules may be implemented using hardware alone (e.g., one or more of the computer processors 720 of a machine (e.g., machine 1800)) or a combination of hardware and software. For example, any of the described modules of the annotation system 206 may physically include an arrangement of one or more computer processors 720 (e.g., a subset of one or more computer processors of a machine (e.g., machine 1800) or one or more computer processors therein) configured to perform the operations described herein for the module. As another example, any module of annotation system 206 may include software, hardware, or both software and hardware that configures an arrangement of one or more computer processors 720 (e.g., in one or more computer processors of a machine (e.g., machine 1800)) to perform operations described herein for that module. Thus, different modules of annotation system 206 may include and configure different arrangements of such computer processors 720 or a single arrangement of such computer processors 720 at different points in time. Further, any two or more modules of annotation system 206 may be combined into a single module, and the functionality described herein for a single module may be subdivided among multiple modules. Furthermore, according to various example embodiments, modules described herein as being implemented in a single machine, database, or device may be distributed across multiple machines, databases, or devices.

The image data receiving module 702 receives image data and depth data captured by the client device 102. For example, the image is a photograph captured by an optical sensor (e.g., camera) of the client device 102. The image includes one or more real world features, such as a face or real world object of the user detected in the image. In some implementations, the image includes metadata describing the image.

The sensor data reception module 704 receives sensor data from the client device 102. The sensor data is any type of data captured by the sensors of the client device 102. In an example, the sensor data may include motion of the client device 102 collected by a gyroscope, touch input or gesture input from a touch sensor (e.g., a touch screen), GPS, or another sensor of the client device 102 that describes a current geographic location and/or motion of the client device 102. As another example, the sensor data may include temperature data indicative of a current temperature as detected by a sensor of the client device 102. As another example, the sensor data may include light sensor data indicating whether the client device 102 is in a dark or light environment.

The image data processing module 706 performs operations on the received image data. For example, various image processing operations are performed by the image data processing module 706, as will be discussed further herein.

The AR effect module 708 performs various operations based on algorithms or techniques corresponding to animations and/or providing visual and/or audible effects to the received image data, as will be further described herein. In one implementation, a given augmented reality content generator may utilize the AR effect module 708 to perform operations for rendering AR effects (e.g., including 2D effects or 3D effects) and the like.

The rendering module 710 performs rendering of the message for display by the messaging client application 104 based on data provided by at least one of the previously mentioned modules. In an example, rendering module 710 utilizes a graphics processing pipeline to perform graphics operations to render messages for display. In an example, the rendering module 710 implements an extensible rendering engine that supports a plurality of image processing operations corresponding to respective augmented reality content generators.

In some implementations, the rendering module 710 provides a graphics system that renders two-dimensional (2D) objects or objects from the three-dimensional (3D) world (real or imaginary) onto a 2D display screen. In some implementations, such a graphics system (e.g., a graphics system included on client device 102) includes a Graphics Processing Unit (GPU) for performing image processing operations and rendering graphical elements for display.

In an implementation, the GPU includes a logical graphics processing pipeline that may receive a representation of a 2D or 3D scene and provide an output representing a bitmap of the 2D image for display. Existing Application Program Interfaces (APIs) have implemented graphics pipeline models. Examples of such APIs include an open graphics library (OPENGL) API and a METAL API. The graphics processing pipeline includes stages that convert a set of vertices, textures, buffers, and state information into image frames on a picture. In an implementation, one of the stages of the graphics processing pipeline is a shader, which may be used as part of a particular augmented reality content generator applied to an input frame (e.g., image or video). A shader may be implemented as code running on a dedicated processing unit (also referred to as a shader unit or shader processor) that typically executes several computing threads, the code being programmed to generate appropriate levels of color and/or special effects for the fragment being rendered. For example, vertex shaders process the attributes of vertices (location, texture coordinates, color, etc.), and pixel shaders process the attributes of pixels (texture values, color, z-depth, and alpha (alpha) values). In some examples, the pixel shader is referred to as a fragment shader.

It should be appreciated that other types of shader processing may be provided. In an example, an entire frame is rendered with a particular sampling rate within a graphics processing pipeline and/or pixel shading is performed at a particular per-pixel rate. In this manner, a given electronic device (e.g., client device 102) operates the graphics processing pipeline to transform information corresponding to objects into a bitmap that can be displayed by the electronic device.

The sharing module 712 generates messages for storage and/or transmission to the messaging server system 108. The sharing module 712 enables sharing of messages to other users and/or client devices of the messaging server system 108.

In an implementation, the augmented reality content generator module 714 causes the display of the selectable graphical items to be presented in a conveyorized arrangement. As an example, a user may utilize various inputs to rotate selectable graphical items onto and off of a display screen in a manner corresponding to a carousel that provides a cyclic view of the graphical items. The conveyor belt arrangement allows a plurality of graphic items to occupy a particular graphic area on the display screen. In an example, the augmented reality content generators may be organized into respective groups for inclusion on a conveyor belt arrangement, enabling rotation through the augmented reality content generators by group.

In the embodiments described herein, 3D face and scene reconstruction that adds Z-axis dimensions (e.g., depth dimensions) to conventional 2D photographs (e.g., X-axis and Y-axis dimensions) may be performed using depth data and image data. This format enables viewers to interact with the message, change the angle/perspective at which the message is rendered by the subject system, and affect the particles and shaders used in rendering the message.

In an example, the viewer interaction input comes from motion while viewing the message (e.g., from a motion sensor of a device displaying the message to the viewer), which in turn translates into a change in the perspective of how the content, particles, and shader are rendered. Interactions may also come from on-screen touch gestures and other device movements.

In an implementation of such a user interface, the selectable graphical items may be presented in a carousel arrangement in which a portion or subset of the selectable graphical items are visible on a display screen of a given computing device (e.g., client device 102). As an example, a user may utilize various inputs to rotate selectable graphical items onto and off of a display screen in a manner corresponding to a carousel that provides a cyclic view of the graphical items. Thus, the conveyor belt arrangement provided in the user interface allows a plurality of graphical items to occupy a particular graphical area on the display screen.

In an example, respective AR experiences corresponding to different AR content generators may be organized into respective groups for inclusion on a conveyor belt arrangement, thereby enabling rotation through media overlays by group. While a conveyor belt interface is provided as an example, it is understood that other graphical interfaces may be used. For example, a set of augmented reality content generators may include a graphical list, a scroll graphic, or another graphical interface that enables navigation through various graphical items for selection, and so forth. As used herein, a conveyor interface refers to displaying graphical items in an arrangement similar to a circular list, enabling navigation through the circular list to select or scroll through the graphical items based on user input (e.g., touch or gesture). In an example, a set of graphical items may be presented on a horizontal (or vertical) line or axis, where each graphical item is represented as a particular thumbnail image (or icon, avatar, etc.). At any one time, some of the graphical items in the conveyor belt interface may be hidden. If the user wants to view a hidden graphical item, in an example, the user may provide user input (e.g., touch, gesture, etc.) to scroll through the graphical item in a particular direction (e.g., left, right, up or down, etc.). Thereafter, a subsequent view of the conveyor interface is displayed, wherein an animation is provided or rendered to render one or more additional graphical items for inclusion on the interface, and wherein some of the previously rendered graphical items may be hidden in the subsequent view. In an embodiment, in this way, a user may navigate back and forth through a collection of graphical items in a circular manner. Thus, it will be appreciated that the conveyor belt interface may optimize screen space by displaying only a subset of images from the collection of graphical items in a cyclic view.

As described herein, the augmented reality content generator may be included on a conveyor belt arrangement (or another interface as discussed above) to enable rotation through the augmented reality content generator. Further, the augmented reality content generator may be selected for inclusion based on various signals including, for example, time, date, geographic location, metadata associated with the media content, and the like.

In some implementations, the messaging system 100 determines a lifetime value (LTV) analysis of the users of the augmented reality content generator based on hard-coded heuristics, but the method may not expand as the number of users within the messaging system 100 increases. The subject technology provides new techniques to determine current and future monetization states of users of augmented reality content generators and to determine monetization potentials of users of augmented reality content generators that are driven by viral (e.g., popular in use) augmented reality content generators to the messaging system 100. The LTV referred to herein may include revenue from online advertising (e.g., advertisements), story advertising, and sponsored creative tools.

The messaging system 100 (or components thereof) provides a technique that addresses the following technical challenges:

1. Making up for gap in monetary user's revenue by augmented reality content generator

In an example, 12% of users of augmented reality content generator Month Active Users (MAUs) are monetized daily in the united states, as compared to an overall level of 60% in the united states;

in the example, 2% of users of the augmented reality content generator MAU are monetized daily on a global scale, with an overall level of 33%;

2. increasing the percentage of LTVs of users of the augmented reality content generator or of the augmented reality content generator among all users

In an example, the LTV of the user of the augmented reality content generator is 13% of the LTV of all users in the United states

In an example, the LTV of the user of the augmented reality content generator is 8% of the LTV of all users worldwide

3. Grouping users of augmented reality content generators into other highly monetized and more similar groups

Since the user of the augmented reality content generator is more passive and has fewer friends than other highly participating groups, a way to turn them into a more similar group is determined, which in an example can be monetized more than 10 times globally on the platform.

Specifically, the messaging system 100 (or components thereof) implements the following methods to solve the above-described problems:

1. Seasonal (e.g., where data may undergo periodic and predictable changes that repeat every calendar year or other period of time) may affect the prediction of the average trading value of the customer. The messaging system 100 (or components thereof) breaks down the time series transaction data into trends and seasonality. In an example, seasonal issues may be more naturally addressed if the messaging system 100 (or components thereof) utilizes longer periods and has a good user-level revenue prediction model from the business.

2. The messaging system 100 (or components thereof) uses the same method to examine the LTV of any experiment designed to increase the monetization value of the user of the augmented reality content generator and quantify the impact from the monetization perspective.

3. The messaging system 100 (or components thereof) incorporates the current analysis into a further development of cluster analysis to better understand the group LTV.

4. The messaging system 100 (or a component thereof) models LTVs for other user roles using the same method.

In some implementations, the messaging system 100 (or a component thereof) provides and utilizes a model to determine the LTV of the user. In an example, the key assumption behind the model is to consider user-level transactions or advertisements as non-contractual scenarios, and the goal is to model the user according to past transaction behavior in both the transaction recency/frequency distribution (transaction recency/frequency distribution) and the transaction monetary value distribution.

To model the transaction recency/frequency distribution, the messaging system 100 (or components thereof) implements a model based on a BG/NBD (beta geometry negative binomial distribution) model after modification according to the pareto/NBD model. The goal is to ensure that the customer, either as an individual or as a whole, follows a particular behavior to have the desired result. In an implementation, the following are key assumptions of the model:

1. multiple transactions by clients follow a poisson process with a transaction rate lambda

2. The heterogeneity of lambda (e.g., population, sample, or result is different) follows a gamma distribution

3. After any transaction, the customer becomes inactive with probability p. Thus, points at which customers "exit" are distributed across transactions according to a (shifted) geometric distribution

4.p heterogeneity follows the beta distribution

5. The transaction rate λ and the exit probability p vary independently across clients.

To model future monetary value, the messaging system 100 (or components thereof) follows a gamma-gamma model (e.g., where the monetary value of a given transaction of a user varies randomly about its average transaction value, the average transaction value varies across the user but does not vary over time for any given individual (user), or the distribution of average transaction values across the user is independent of the transaction process) to predict monetary value, and the user profile follows the following general criteria:

1. The monetary value of a given transaction by a customer varies randomly around its average transaction value.

2. The average trading value varies across customers but does not vary over time for any given individual.

3. The distribution of average trading value across customers is independent of the trading process.

As shown in graph 800, the user of the AR content generator has a much higher permeability in the MAU, increasing from 25% to over 30% after the AR content generator is used for facial effects. For the us market, chart 800 shows a very similar trend, showing that the user permeability of AR content generators ranges from 8% to over 10%.

As shown in graph 900, although users of AR content generators account for almost one third of MAUs, the percentage of MAUs monetized daily is low. Only about 12% of users in the United States (US) AR content generators are monetized daily, while approaching 60% of MAUs in the united states at an overall level. In view of the possible increase in size of the user group over time, there is still much room for increasing the number over time.

For customer LTV analysis, the discussion further herein focuses primarily on the us market as it is the most monetized market and will give a better understanding in terms of future monetization expectations and direction. Because of the size of the user, sampling is used to expedite the training data preparation process. For monetization value prediction, a discount rate of 5% is assumed.

As shown in Table 1 below, the users of the AR content generator reduced their average LTV by about 30% [ post $2.42 and pre $3.43] after these users use the AR content generator for facial effects. As also shown in table 1, this is driven by the LTV of the new users of the AR content generator being much lower than before the AR content generator is facial-effects [ new users are $2.09 after facial-effects and $3.43 before ], which pulls down the average LTV of all users of the AR content generator after the AR content generator is facial-effects (e.g., after these users use the AR content generator to facial-effects).

TABLE 1 summarized average LTV at the end of year 2 for different user groups assuming a discount rate of 0.05

Meanwhile, as shown in the following table 2, after the AR content generator performs the facial effect, the cumulative revenue of all users is slightly higher [ back $16.88M and front $16.73M ]. The AR content generator for the facial effect may not substantially improve the overall monetization opportunity of the users of the AR content generator, only increase revenue by 1%, but there is room for the users of the light or newly participating AR content generator to improve monetization possibilities, and cluster analysis may be performed on the users of the AR content generator before and after the facial effect is performed on the AR content generator.

TABLE 2 summarized cumulative LTV at the end of year 2 for different user groups of the AR content generator assuming a discount rate of 0.05

As shown in Table 1 above, the average LTV worldwide is about 36% of the US LTV [ $0.86 worldwide versus $2.42 in the United states ], but in view of its greater amount in the International market it increases more revenue by about 46% to accumulated revenue [ $24.60M versus $16.88M ]. Even though the us user of the AR content generator has been relatively well monetized, its LTV is only 13% of the total users in the us $ user of the AR content generator $2.42 with all users $18.05].

In the following discussion related to model verification, the messaging system 100 (or components thereof) uses the time frames 09/01/19 and 12/31/19 to build a model and verify. This is done to protect the user from the effects of the AR content generator on the face in the summer and to wait for the new user to be eligible to see the advertisement. In an embodiment, there are two ways to check how the model performs:

1. using the entire time period to check how the actual compares to the model for repeat transactions and comparing differences

2. There is a short hold period from this time to test model accuracy for the frequency of user transactions.

In some implementations, as shown in fig. 10, the messaging system 100 (or a component thereof) can determine actual and model comparisons at different transaction frequencies.

FIG. 10 illustrates an example chart 1000 of sample full time period model verification according to some embodiments.

In an embodiment, the messaging system 100 (or components thereof) is calibrated using 09/01/19 to 11/30/19 and the hold test is performed using 12/01/19 and 12/31/19.

FIG. 11 illustrates an example chart of sample hold period model validation according to some embodiments.

In this example, graph 1100 shows the cumulative error rate over the calibration period until the purchase frequency is 9, with the maximum data flow being shown for the purchase frequency of 9. The model is reasonably accurate except that a large group of users, such as all users in the united states, are after the AR content generator has performed the facial effects. Accuracy can be improved by modeling subsets or groups of users individually and training and testing with longer periods. In an example, the purchase frequency up to a value of 9 in the chart 1100 corresponds to the cumulative number of transactions over a calibration period (e.g., 09/01/19 to 11/31/19), which is set to this upper limit to provide a more accurate base error case. In an example, an accumulated error rate below a predetermined percentage (e.g., 5%) indicates that the model is accurate.

The method 1600 may be embodied in computer readable instructions for execution by one or more computer processors such that the operations of the method 1600 may be performed in part or in whole by the messaging system 100; accordingly, method 1600 is described below by way of example with reference thereto. However, it should be understood that at least some of the operations of the method 1600 may be deployed on a variety of other hardware configurations, and that the method 1600 is not intended to be limited to the messaging system 100, and may be performed by components of the messaging client application 104 or the annotation system 206.

At operation 1602, the messaging system 100 determines a Monthly Active User (MAU) and permeability of global users and users in a particular country. In an embodiment, the messaging system 100 determines that the user of the at least one AR content generator has a higher permeability in the MAU. The messaging system determines that the percentage of daily monetized users is lower than the percentage of users of the at least one AR content generator.

At operation 1608, the messaging system 100 selects at least one Augmented Reality (AR) content generator based at least in part on the determined lifetime value of the user of the particular country. In an embodiment, the at least one AR content generator is selected based at least in part on determining that a percentage of daily monetization users is lower than a percentage of users of the at least one AR content generator.

At operation 1610, the messaging system 100 causes at least one AR content generator to be displayed at the client device. In an embodiment, a messaging system provides at least one AR content generator for display at a particular client device associated with at least one new user of the new set of users, wherein the new set of users is selected to enhance monetization based on revenue from online advertising and sponsored creative tools.

Fig. 17 is a block diagram illustrating an example software architecture 1706 that may be used in connection with the various hardware architectures described herein. FIG. 17 is a non-limiting example of a software architecture, and it should be appreciated that many other architectures can be implemented to facilitate the functionality described herein. The software architecture 1706 may execute on hardware such as the machine 1800 of fig. 18, which includes a processor 1804, memory 1814, and (input/output) (I/O) components 1818, among others. A representative hardware layer 1752 is illustrated and may represent, for example, the machine 1800 of fig. 18. Representative hardware layer 1752 includes processing unit 1754 that has associated executable instructions 1704. The executable instructions 1704 represent executable instructions of the software architecture 1706, including implementations of the methods, components, etc. described herein. The hardware layer 1752 also includes memory and/or storage module memory/storage 1756 that also has executable instructions 1704. Hardware layer 1752 may also include other hardware 1758.

In the example architecture of fig. 17, the software architecture 1706 may be conceptualized as a stack of layers in which each layer provides a particular function. For example, the software architecture 1706 may include layers such as an operating system 1702, libraries 1720, framework/middleware 1718, applications 1716, and presentation layer 1714. Operationally, applications 1716 and/or other components within the layer may call API call 1708 through a software stack and receive a response to API call 1708 as in message 1712. The layers shown are representative in nature and not all software architectures have all layers. For example, some mobile operating systems or dedicated operating systems may not provide framework/middleware 1718, while other operating systems may provide such a layer. Other software architectures may include additional or different layers.

The operating system 1702 may manage hardware resources and provide common services. The operating system 1702 may include, for example, cores 1722, services 1724, and drivers 1726. Core 1722 may serve as an abstraction layer between hardware and other software layers. For example, core 1722 may be responsible for memory management, processor management (e.g., scheduling), component management, networking, security settings, and the like. The service 1724 may provide other common services to other software layers. The driver 1726 is responsible for controlling or interfacing with the underlying hardware. For example, the driver 1726 includes a display driver, an imaging device driver, and a camera driver according to a hardware configuration, Driver, flash memory driver, serial communication driver (e.g., universal Serial Bus (USB) driver), and the like>Drivers, audio drivers, power management drivers, etc.

Library 1720 provides a common infrastructure used by applications 1716 and/or other components and/or layers. Library 1720 provides functionality that allows other software components to perform tasks in an easier manner than directly interfacing with the functionality of underlying operating system 1702 (e.g., cores 1722, services 1724, and/or drivers 1726). The library 1720 may include a system library 1744 (e.g., a C-standard library), and the system library 1744 may provide functions such as memory allocation functions, string manipulation functions, mathematical functions, and the like. In addition, libraries 1720 may include API libraries 1746, such as media libraries (e.g., libraries that support presentation and manipulation of various media formats such as MPREG4, H.264, MP3, AAC, AMR, JPG, PNG), graphics libraries (e.g., openGL framework that may be used to render 2D and 3D with graphics content on a display), database libraries (e.g., SQLite that may provide various relational database functions), web libraries (e.g., webKit that may provide web browsing functions), and the like. Library 1720 may also include various other libraries 1748 to provide many other APIs to applications 1716 and other software components/modules.

The framework/middleware 1718 (also sometimes referred to as middleware) provides a higher level of public infrastructure that can be used by applications 1716 and/or other software components/modules. For example, the framework/middleware 1718 may provide various Graphical User Interface (GUI) functions, advanced resource management, advanced location services, and the like. The framework/middleware 1718 can provide a wide variety of other APIs that can be used by applications 1716 and/or other software components/modules, some of which can be specific to a particular operating system 1702 or platform.

Applications 1716 include built-in applications 1738 and/or third party applications 1740. Examples of representative built-in applications 1738 may include, but are not limited to, a contact application, a browser application, a book reader application, a location application, a media application, a messaging application, and/or a gaming application. Third party applications 1740 may include the use of ANDROID by entities other than the vendor of the particular platform ^TM Or IOS ^TM An application developed in a Software Development Kit (SDK) and may be in a software application such as an IOS ^TM 、ANDROID ^TM 、Mobile operating system of the phone or other mobile software running on the mobile operating system. Third party application 1740 may call API call 1708 provided by the mobile operating system (e.g., operating system 1702) to facilitate the functionality described herein.

Applications 1716 may use built-in operating system functionality (e.g., cores 1722, services 1724, and/or drivers 1726), libraries 1720, and framework/middleware 1718 to create a user interface to interact with a user of the system. Alternatively or additionally, in some systems, interaction with the user may occur through a presentation layer, such as presentation layer 1714. In these systems, the application/component "logic" may be separate from aspects of the application/component that interact with the user.

In particular, fig. 18 shows a schematic representation of a machine 1800 in the form of an example of a computer system in which instructions 1810 (e.g., software, programs, applications, applets, apps, or other executable code) for causing the machine 1800 to perform any one or more of the methods discussed herein may be executed in the machine 1800. Likewise, instructions 1810 may be used to implement the modules or components described herein. The instructions 1810 transform a generic, un-programmed machine 1800 into a specific machine 1800 that is programmed to perform the functions described and illustrated in the manner described. In alternative embodiments, machine 1800 operates as a standalone device or may be coupled (e.g., networked) to other machines. In a networked deployment, the machine 1800 may operate in the capacity of a server machine or a client machine in server-client network environment, or as a peer machine in a peer-to-peer (or distributed) network environment.

Furthermore, while only a single machine 1800 is illustrated, the term "machine" shall also be taken to include a collection of machines that individually or jointly execute instructions 1810 to perform any one or more of the methodologies discussed herein.

The machine 1800 may include a processor 1804, which includes processors 1808 through 1812, memory/storage 1806, and I/O components 1818, which may be configured to communicate with each other, for example, via a bus 1802. The memory/storage 1806 may include memory 1814, such as main memory or other storage, and storage unit 1816, with the processor 1804 being able to access both the memory 1814 and the storage unit 1816, e.g., via the bus 1802. The storage unit 1816 and the memory 1814 store instructions 1810 embodying any one or more of the methods or functions described herein. The instructions 1810 may also reside, completely or partially, within the memory 1814, within the storage unit 1816, within at least one of the processors 1804 (e.g., within a cache memory of a processor), or any suitable combination thereof, during execution thereof by the machine 1800. Accordingly, the memory 1814, the storage unit 1816, and the memory of the processor 1804 are examples of machine-readable media.

I/O components 1818 may include a variety of components that receive input, provide output, generate output, transmit information, exchange information, capture measurements, and so forth. The particular I/O components 1818 included in a particular machine 1800 will depend on the type of machine. For example, a portable machine such as a mobile phone will likely include a touch input device or other such input mechanism, while a headless server machine will likely not include such a touch input device. It will be appreciated that the I/O component 1818 may include many other components not shown in FIG. 18. The I/O components 1818 are grouped by function only to simplify the following discussion and the grouping is in no way limiting. In various example embodiments, the I/O components 1818 may include an output component 1826 and an input component 1828.

The positioning component 1838 may include a position sensor component (e.g., a GPS receiver component), an altitude sensor component (e.g., an altimeter or barometer from which an altitude is detected, an orientation sensor component (e.g., a magnetometer), and so forth.

Communication may be accomplished using a variety of techniques. The I/O components 1818 may include a communication component 1840 that is operable to couple the machine 1800 to the network 1832 or the device 1820 via the coupling 1824 and the coupling 1822, respectively.

"processor" refers to any circuit or virtual circuit (physical circuit emulated by logic executing on an actual processor) that manipulates data values according to control signals (e.g., "commands," "operation code," "machine code," etc.) and generates corresponding output signals that are applied to operate the machine. For example, the processor may be a Central Processing Unit (CPU), a Reduced Instruction Set Computing (RISC) processor, a Complex Instruction Set Computing (CISC) processor, a Graphics Processing Unit (GPU), a Digital Signal Processor (DSP), an Application Specific Integrated Circuit (ASIC), a Radio Frequency Integrated Circuit (RFIC), or any combination thereof. A processor may also be a multi-core processor having two or more separate processors (sometimes referred to as "cores") that may execute instructions simultaneously.

"machine storage medium" refers to a single or multiple storage devices and/or media (e.g., a centralized or distributed database, and/or associated caches and servers) that store the executable instructions, routines, and/or data. Thus, the term should be taken to include, but is not limited to, solid-state memory, as well as optical and magnetic media, including memory internal or external to the processor. Specific examples of machine, computer, and/or device storage media include: nonvolatile memory including, for example, semiconductor memory devices such as erasable programmable read-only memory (EPROM), electrically erasable programmable read-only memory (EEPROM), FPGA, and flash memory devices; magnetic disks, such as internal hard disks and removable disks; magneto-optical disk; CD-ROM and DVD-ROM disks.

The terms "machine storage medium," computer storage medium, "and" device storage medium "expressly exclude carrier waves, modulated data signals, and other such medium, at least some of which are contained within the term" signal medium.

"component" refers to a device, physical entity, or logic having boundaries defined by function or subroutine calls, branch points, APIs, or other techniques that provide partitioning or modularization of particular processing or control functions. The components may interface with other components via their interfaces to perform machine processing. A component may be part of a program designed for a packaged functional hardware unit for use with other components and which typically performs the specific functions of the relevant function. The components may constitute software components (e.g., code embodied on a machine-readable medium) or hardware components. A "hardware component" is a tangible unit capable of performing certain operations and may be configured or arranged in some physical manner. In various example embodiments, one or more computer systems (e.g., stand-alone computer systems, client computer systems, or server computer systems) or one or more hardware components of a computer system (e.g., processors or groups of processors) may be configured by software (e.g., an application or application part) as hardware components for performing certain operations as described herein. The hardware components may also be implemented mechanically, electronically, or in any suitable combination thereof. For example, a hardware component may include specialized circuitry or logic permanently configured to perform certain operations. The hardware component may be a special purpose processor such as a Field Programmable Gate Array (FPGA) or an Application Specific Integrated Circuit (ASIC). The hardware components may also include programmable logic or circuitry that is temporarily configured by software to perform certain operations. For example, the hardware components may include software that is executed by a general purpose processor or other programmable processor. Once configured by such software, the hardware components become the specific machine (or specific components of the machine) that is uniquely customized to perform the configured functions and is no longer a general purpose processor. It will be appreciated that decisions for hardware components may be driven for cost and time considerations, either in dedicated and permanently configured circuits or mechanically in circuits configured briefly (e.g., by software configuration). Thus, the phrase "hardware component" (or "hardware-implemented component") should be understood to encompass a tangible entity, i.e., an entity that is physically constructed, permanently configured (e.g., hardwired), or temporarily configured (e.g., programmed) to operate in a manner or to perform certain operations described herein. Considering embodiments in which hardware components are temporarily configured (e.g., programmed), there is no need to configure or instantiate each of the hardware components at any one time. For example, where the hardware components include a general-purpose processor configured as a special-purpose processor by software, the general-purpose processor may be configured as different special-purpose processors (e.g., including different hardware components) at different times, respectively. The software configures one or more particular processors accordingly to constitute particular hardware components, for example, at one time, and to constitute different hardware components at different times. A hardware component may provide information to and receive information from other hardware components. Thus, the described hardware components may be considered to be communicatively coupled. Where multiple hardware components are present at the same time, communication may be achieved by signal transmission between or among two or more hardware components (e.g., via appropriate circuitry and buses). In embodiments in which multiple hardware components are configured or instantiated at different times, communication between such hardware components may be achieved, for example, by storing information in a memory structure accessed by the multiple hardware components and retrieving information in the memory structure. For example, one hardware component may perform an operation and store the output of the operation in a memory device to which it is communicatively coupled. Other hardware components may then access the memory device at a later time to retrieve the stored output and process it. The hardware component may also initiate communication with an input device or an output device, and may operate on a resource (e.g., collection of information). Various operations of the example methods described herein may be performed, at least in part, by one or more processors that are temporarily configured (e.g., via software) or permanently configured to perform the relevant operations. Whether temporarily configured or permanently configured, such a processor may constitute a processor-implemented component that operates to perform one or more operations or functions described herein. As used herein, "processor-implemented components" refers to hardware components implemented using one or more processors. Similarly, the methods described herein may be implemented, at least in part, by processors, with particular one or more processors being examples of hardware. For example, at least some of the operations of the method may be performed by one or more processors or processor-implemented components. In addition, the one or more processors may also be operative to support execution of related operations in a "cloud computing" environment or to operate as a "software as a service" (SaaS). For example, at least some of the operations may be performed by a computer group (as an example of a machine comprising a processor), where the operations are accessible via a network (e.g., the internet) and via one or more suitable interfaces (e.g., APIs). The performance of certain operations may be distributed among processors, not residing within a single machine, but rather deployed across multiple machines. In some example embodiments, the processor or processor-implemented components may be located in a single geographic location (e.g., within a home environment, an office environment, or a server farm). In other example implementations, the processor or processor-implemented components may be distributed across several geographic locations.

"carrier signal" refers to any intangible medium capable of storing, encoding or carrying instructions for execution by a machine, and includes digital or analog communications signals or other intangible medium to facilitate communication of such instructions. The instructions may be transmitted or received over a network via a network interface device using a transmission medium.

"computer-readable medium" refers to both machine storage media and transmission media. Accordingly, these terms include both storage devices/media and carrier wave/modulated data signals. The terms "machine-readable medium," "computer-readable medium," and "device-readable medium" mean the same thing and may be used interchangeably in this disclosure.

"client device" refers to any machine that interfaces with a communication network to obtain resources from one or more server systems or other client devices. The client device may be, but is not limited to, a mobile phone, desktop computer, laptop computer, portable Digital Assistant (PDA), smart phone, tablet computer, super book, netbook, laptop computer, multiprocessor system, microprocessor-based or programmable consumer electronics, game console, set top box, or any other communication device that a user can use to access a network. In this disclosure, a client device is also referred to as an "electronic device".

"ephemeral message" refers to a message that is accessible for a limited duration of time. The transient message may be text, images, video, etc. The access time for the ephemeral message may be set by the message sender. Alternatively, the access time may be a default setting or a setting specified by the recipient. The message is temporary regardless of the setup technique.

"communication network" refers to one or more portions of a network, the network may be an ad hoc network, an intranet, an extranet, a Virtual Private Network (VPN), a Local Area Network (LAN), a Wireless LAN (WLAN), a Wide Area Network (WAN), a Wireless WAN (WWAN), a Virtual Private Network (VPN) Metropolitan Area Networks (MANs), the Internet, portions of the Public Switched Telephone Network (PSTN), plain Old Telephone Service (POTS) networks, cellular telephone networks, wireless networks, A network, other type of network, or a combination of two or more such networks. For example, the network or portion of the network may comprise a wireless network or cellular network, and the coupling may be a Code Division Multiple Access (CDMA) connection, a global system for mobile communications (GSM) connection, or other type of cellular or wireless coupling. In this example, the coupling may implement any of a variety of types of data transmission techniques, such as single carrier radio transmission techniques (1 xRTT), evolution data optimized (EVDO) techniques, general Packet Radio Service (GPRS) techniques, enhanced data rates for GSM evolution (EDGE) techniques, and so forth,Third generation partnership project (3 GPP), fourth generation wireless (4G) networks, universal Mobile Telecommunications System (UMTS), high Speed Packet Access (HSPA), worldwide Interoperability for Microwave Access (WiMAX), long Term Evolution (LTE) standards, other data transmission technologies defined by various standards setting organizations, other long distance protocols, or other data transmission technologies.

"component" refers to a device, physical entity, or logic having boundaries defined by function or subroutine calls, branch points, APIs, or other techniques that provide partitioning or modularization of particular processing or control functions. Components may be combined with other components via their interfaces to perform machine processes. A component may be part of a program designed for a packaged functional hardware unit for use with other components and which typically performs the specific functions of the relevant function. The components may constitute software components (e.g., code embodied on a machine-readable medium) or hardware components. A "hardware component" is a tangible unit capable of performing certain operations and may be configured or arranged in some physical manner. In various example embodiments, one or more computer systems (e.g., stand-alone computer systems, client computer systems, or server computer systems) or one or more hardware components of a computer system (e.g., processors or groups of processors) may be configured by software (e.g., an application or application part) as hardware components for performing certain operations as described herein. The hardware components may also be implemented mechanically, electronically, or any suitable combination thereof. For example, a hardware component may include specialized circuitry or logic permanently configured to perform certain operations. The hardware component may be a special purpose processor such as a Field Programmable Gate Array (FPGA) or an Application Specific Integrated Circuit (ASIC). The hardware components may also include programmable logic or circuitry that is temporarily configured by software to perform certain operations. For example, the hardware components may include software that is executed by a general purpose processor or other programmable processor. Once configured by such software, the hardware components become specific machines (or specific components of machines) that are uniquely customized to perform the configured functions and are no longer general purpose processors. It will be appreciated that decisions for hardware components may be driven for cost and time considerations, either in dedicated and permanently configured circuits or mechanically in circuits configured briefly (e.g., by software configuration).
